C series (Honda)

Started in 1963 with pushrods, then 1966 it went OHC, there have been some 21 million produced, and still being produced in (at various times) 11 countries. Original model was the probably the 49(50)cc model, and there were 70's, 90's and 100's all sorts of permutations, but it is the original step-thru. Three speed, auto clutch, kick and electric start.
